  1. 1-D Synthetic Seismic Model Zaid AlMusallam SAGE 2004

  2. Outline • Objective • Definition • Reflection Data • Synthetic Model • Comparison • Conclusion

  3. Objective Determine the thickness of the Basalt layer

  4. SyntheticSeismogram’s Def’n • “An Artificial seismic reflection record manufactured by assuming that a particular waveform travels through an assumed model” • “A 1D sythetic seismogram is formed by simply convolving an embeded waveform with a reflectivity function” From E. D. A. G.

  5. Seismic Reflection Profile

  6. Thin Layer Time (sec)

  7. Design • Matlab Code • Parameters • Resulting Model

  8. Depth Velocity Model

  9. Synthetic Seismogram

  10. Reflections Time (sec)

  11. Comparison Time (sec)

  12. Basalt thickness equals 45 m Velocity through Basalt is 3.2 km/s ModelParameters

  13. Conclusion Zbasalt = 45 m
